Enter the number of the string parameter in which the

TNC is to save the copied string. Confirm with the

ENT key

Enter the number of the QS parameter from which the

substring is to be copied. Confirm with the ENT key

Enter the number of the place starting from which to

copy the substring, and confirm with the ENT key

Enter the number of characters to be copied, and

string parameter QS10 beginning with the third character (BEG2)

Remember that the first character of a text sequence

starts internally with the zeroth place.
